It has to be dark enough for the backlit keyboard to work I think.
When it is dark you should be able to manually control it using the F8, F9, and F10 keys. If that doesn't work try holding the "fn" key when you hit the F keys.
Looking back at some of your previous posts, it appears that you have a 15" 1.25 GHz PB...is that right? That model did come with the backlit keyboard, so it should work. (The 1.0 GHz model released at the same time did not have the backlit keyboard.) Hmm...

I'm not sure if it was replaced or not, i got it from a friend. I don't really care about the backlit that much, it would just be cool to have one in awhile.
